The Marius is the best board I have ever ridden. We worked hard to make changes that would keep the overall ride characteristics while increasing the speed. We also wanted the board to be capable of the highest level of boat riding but also good for rail riding. The changes made are what I consider to be the perfect board. The Marius has low drag while riding flat and is fast edge to edge. It holds edge up off the wake which results in more pop. The dual center spine and continuous rocker aid in super soft landings. For cable riding you can remove the aluminum fin. The beveled edge rail makes the board more durable as the board edge does not come in contact with rail. The versatility of the Marius is unprecedented. I use it behind the boat, at the cable, winching and on rails. We worked hard to make a shape riders would enjoy and progress their riding to the next level. We succeeded.
